To all wfiom z't may concern: 1

Be it known that I, lfninrriin'r J. Bnnnnn,

a citizen of the United States, and a resident of St. Louis, in the State of Missouri,

5 have inventedcertain new and useful limm'ovements inCorner Brackets and Fasteners for Screen Frames and the like, of which the following is a specification.

My present invention relates generally to screen frames and more particularly to means for fastening the corners thereof, my object being the provision of a simple device by means of which. the corners of screen frames may be rigidly connected and in such manner as to obviate the necessity of a skilled mechanic in the assembling opera tion.

A still further object is the provision of a simple inexpensive device which may be readily and cheaply manufactured and by means of which the side and end rails of screen frames may be rigidly and perinanently connected in butt joint relation so as to avoid the necessity of skilled workmen.

In the accompanying drawing which illustrates my present invention and forms a part of this specification,

Figure 1 is a perspective view illustrating through Referring now to these figures and par ticularly' to Figures 1 2 and 3 my inven tion proposes the utilization of rails 10 and 11 in the formation of screen frames and the like, having lengthwise grooves 12 in the opposite faces thereof, extending along and in parallel adjacent relation to the side edges thereof and my invention further proposes the formation of a screen frame by means of the rails 10 and 11 disposedin the butt jointed relation shown in Figure 1 so as to avoid the necessity for more or less skillful mitering. c

F or use in connection with rails and a joint of the above described type my invention proposesa brace and connecting member which as seen particularly in Figure 4: is formed from a single piece of sheet metal with parallel side plates 13' and 14: bent angularly in the same direction froinopposite sides of a flat connecting or base portion 15, these side plates 13 and 1 1 having along their side edges inturned flanges 16 adapted to extend into the grooves 12 of one of the abutting rails for instance therail 10 in the oint shown in Figure 1. For this purpose theside plates 13 and 1 1- .are spaced. 1 apart a distance adapted to receive one end of the rail 10 therebetween, the extremity of the rail 10 being seated on the flat connect ing or base piece 15 as clearly shown in Figures 1 and 2. I

The side plates 13 and lsalso have apertures 17 to receive screws and the like 18 extending into the material of the'rail 10 14, their central portions are struck-out therefrom and bent in parallel relation from opposite sides of the connecting or base' piece 15 and in a direction opposite to the extension of the side plates 13 and 14, to

form side wings 19 adapted to embrace the side surfaces of the rail 11 against'which the end of the rail 10 with the connecting or base piece 15 seats. Eaclrof these side wings 19 is also provided with an integrally struck-uptongue 20 projecting at right angles thereto and bent inwardly, the two tongues beingin opposing relation and so spaced from the'base or connecting piecejla as to be engageable within the adjacent groove 12 of the rail 11 as clearly shown in Figures 1 and 2. i

Like the side plates 13 and 1 1 the op-u,

positively extending rail embracing wings 19 have apertures 21 adapted to receive screws and like fastening members 22 extending into the material of the rail 11 and thus it is obvious that the complete joint will be rigidfand permanent and may be completed with but slight instruction in the hands of'unskilled persons.

I claim: if

A brace and connecting member for siinilarly formed angularrails in butt'jointed relation having parallel grooves in their. side faces ad3acent to their opposite edges, consistingof a section of sheet metal having a base piece and parallel side plates extending in one direction from the base piece of less width than said rails and adapted to embraceone end of a rail disposed therebetween and in endwlee engagement with the base piece; said side plateshaving inturned flanges along their opposite sides adapted to project into'the grooves of the said rail endandalso having apertures for the reception" of fastening screws and the like, side Wings struck-up from the said side plates and extending in parallel spaeed re- 10 lation from the said base piece in the opposite direction to said side plates to transversely embrace opposite sldes'ot the other rail and havlng lntegral tongues struckup therefrom and projecting transversely the reception of fastening means.
